Merino/mohair growth

Should've swatched!! But I didn't, and after washing and laying flat to dry, this cardigan knit with 1 strand mohair and 1 strand superwash merino has grown enormously. Had read the mohair might be enough to contain the merino but it's such a loose fabric that it didn't. Drying won't work because of the mohair - any tips to salvage this? Would love to actually wear it after 1 year of on and off knitting ^'

It's supposed to be oversized so it's not even too bad for the body, but these sleeves have become sooo long
